creating new work sheet from data entered in a column

Absolute Beginner,

I have attached a spreadsheet showing 3 work sheets.

Master has all items which could be selected.

Worksheet 5301 is created after pressing calculate button when a figure is placed in the qty field of a column.
Master sheet resets to clear fields in Qty column ready for next apartment.


A macro or option would be greatly appreciated.

Cheers!
Glenn
